IMPROVEMENT IN FAN ATTACHMENTS FOR TABLES.

Speciiieation forming part of Letters Patent No. 116,919, dated July 1l,1871.

To all Iwhom it may concern: Y

Be it known that we, THOMAS S. YBINKARD and ROBERT H. BoAL, of Urbana,Champaign county, Ohio, have invented a new and usei'ul Fan Attachmentfor Tables, Smc., of which the following is a specification:

Our invention. relates to a fly-fan or punka, adapted for attachment toa table, and operated by a treadle placed conveniently to one of thepersons sitting at the table.

Figure l is a perspective view of our fan in position. Fig. 2 isa'vertical section of the post or column to a larger scale.

A may represent a dining-table. B is a foot or tripod, from whose centerrises a hollow post or column, C. The standard B C, thus formed, hasiirmly fastened to and projecting from it an elastic clamp, D, whoseprojections d and terminal lip cl tightly grasp without cutting ordenting the table. The post C contains a shaft, E, from whose upperportion, above the standard, there project arms F, having eyes f, forthe engagement of thehooks g at the inner ends of stems G of fans G g.The arms F terminate in racks H, guarded by spring-retaining fingers h,that securely hold the stems G in any one of the notches oftheirrespective racks, thus permitting the fans to hang at any desired orconvenient elevation or depression. The lower end of the shaft E has acrank, e, connected, by rod I, with a bell-crank, J, journaled in eyes dof the clamp; and the opposite extremity of this bell-crank connects, byrod K, with an arm, L, that projects upward from treadle M, journaled ina pedestal,

N, that is secured to the floor by wood screw O, or other means. Acruet-stand, P, or other convenient appendage, may be applied to thestandard B O.

The motion of the fan being vibratory, the vanes may be made of unequallength for use on an oblong table, as in the present illustration.

The standard being secured to the middle of the table by engaging thejaws oi' the elastic clamp over its edge, the fans proper or vanes areadjusted in their racks so as to hang higher or lower, as desired. Aperson sitting at the table then, resting his foot on the treadle,vibrates the fan with little or no effort, and with his arms and handsentirely at liberty.

We claim as new and of our inventionl. The combination and arrangementof the standard B C, armed shaft E F, racks H, retaininggiingers lL, andadjustable vanes G g, substantially as and for the purposes set forth.

2. The combination ofthe elastic clamp D d rl with the fan attachment,constrcted and operating as speciiied.

3. The combination of the treadle M N, arms L J J, rods I, and clamp D dd d. with the fan attachment, substantially as described.

In testimony of which invention vwe hereunto set our hands.
